MF_SOURCE_READER_PASSTHROUGH_MODE attribute

When this attribute is set, the Source Reader passes through video samples backed by the system memory to internal MFTs without automatically copying them into a DirectX texture, even if a Direct3D device manager is present.

Data type

BOOL stored as UINT32

Get/set

To get this attribute, call IMFAttributes::GetUINT32.

To set this attribute, call IMFAttributes::SetUINT32.

Remarks

The constant MF_SOURCE_READER_PASSTHROUGH_MODE is not defined in a Windows SDK header file so the caller must specify the GUID value to reference the attribute.
